AIRSHIP.

Specification of Letters Patent.

Application filed April 25, 1919. Serial No. 292,768.

To all whom it may concern:

Be it known that I, JOHANN SCH ETTE, citizen of the German Republic, residing at Zeesen-Koenigs-lvusterhausen, near Berlin, Germany; have invented certain new and useful Improvements in Air-ships, (for which I tiled an application for patent in Germany March 18, 1916, patent allowed under No. 300.180,) of which the following is a specification.

The framework of an airship of the usual rigid type consists essentially of a plurality of longitudinal beams and of rings. Each ring has the shape of a polygon, the number of the sides of which is generally determined by the number of longitudinal beams. The

rings themselves are usually internally.

braced by a number of ties, which, con structed in any suitable manner couple the junction points of the sides of the r ng, so that it is practically impossible for them to be deformed. Besides the normal stresses caused by the gas pressure transmitted to them by the longitudinal beams. these rings have frequently to carry independent loads, which generally must act on such unction points, which are already under heavy strains, or which by their posltion are less suited for such purposes. Thereby exceptionally heavy stresses may be produced in some of the rods of such ring bodies, which may, under circumstances, lead to inadmissibly high deformations-of the rings. In order to avoid such danger, the present 111- velrtion provides that one or several trellis beams are disposed within the plane of such rings in such a manner that the load is re-' ceived, not as heretofore by the ring itself, but by said trellis beams and transmitted by the latter to any desired number of junction points of the ring situated in favorable positions.

Owing to the peculiar character of the strains acting upon such rings of rigid airships forces may appear, which tend to force the ties of the ring or parts thereof from the normal plane. The individual rods of the trellis beam are either partly or all preferably hinged to the junction points of the sides of the ring so that they may be able to follow any deviation of the plane of the ring.

In the accompanying drawings:

Figure 1. is a diagrammatic View showing the framework of an airship through a section, and showing particularly the position and arrangement of the trellis work of the present invention.

Figure 2. is a similar view showing a different arrangement of the trellis work of the present invention.

Figure 3. shows a section of a ring which connects the longitudinal beams, showing the junction point of the trellis work beam with the latter's hinged connection thereto.

Figure 4. is a detail of one of the beams of the trellis work.

Figure is a transverse section of the beam shown in Figure l.

In the drawing, (1 indicates the rings, 6 indicates the trellis beams disposed in the plane of the ring. and 0 indicates the ties carrying the load.

In Figure. l. a one unit trellis work is provided, while in Figure 2, a double unit trellis work is employed. Each of the units in Figure 2 are connected to the ring by three-part beams, and are provided with ties (1 extending downward to the point at which the load is connected thereto.

In Figure 3. there is shown one of the longitudinal beams e and a ring junction point 7'. i This view shows how the beam h of the trellis work is hinged or pivotally connected to the junction point 7'. One form of beam which may be used in the trellis work is shown in Figures 4 and 'hat I claim is:

1. A frame work for airships of the rigid type comprising longitudinal beams; rings connected to said longitudinal "beams to maintain the same in proper position; and load carrying means comprising trellis work having beams connected to a ring at a plurality of points for distributing a load over a pre-determined section of said ring.

2. A frame work for airships of the rigid type comprising longitudinal beams; rings connected to said longitudinal beams to maintain the same in proper position, and load carrying means comprising trellis work having beams lying in the plane of one of said rings and connected to said ring at a plurality of points for distributing a load over a predetermined section of said ring.

3. A f ame work for airships of the rigid type comprising longitudinal beams; rings connecting said beams: diametrical braces connected to said beams to assist the rings in sustaining the normal strain on the beams: and load carrying means comprising trellis work having beams connected to a Patented May t 19324- ring at a plurality of points for distributing type comprising longitudinal beams; rings connecting said beams; and load distributing means comprising trellis work, the latter comprising a plurality of beams connected to the upper portion of a ring at a plurality of points to distribute the load equally over the upper portion of the ring.

)[A frame work for airsliips of the rigid type comprising longitudinal beams; rings connecting said beams; trellis work having beams connected to a ring at a plurality of points; and load carrying beams connected to said trellis work, the latter through its beams connected to the ring distributing the load over a predetermined section of the ring.

6. A frame work for airships of the rigid type comprising longitudinal beams; rings connected to said longitudinal beams to maintain the same in proper position; and load carrying means comprising trellis work having beams pivotally connected to a ring at a pluralityof points for distributing a load over a predetermined section of said ring.

7. A frame work for airships of the rigid type comprising longitudinal beams; rings connecting said" beams; and load carrying means comprising trellis work having beams lying in the plane of one of said rings and pivotally connected to said ring at a plurality of points for distributing a load over a predetermined section of said ring.

In testimony whereof I have aflixed my signature.
